How thick is the septum required between punched holes in a dental dam?

The thickness of the septum between punched holes in a dental dam is crucial for maintaining isolation and preventing tears during dental procedures. A thickness of 3 to 3.5 mm is typically recommended as it strikes a balance between providing adequate support to each section of the dental dam while ensuring that the material remains flexible enough to conform to the contours of the tooth structures being treated. This thickness helps to reduce the risk of saliva or other fluids leaking into the treatment area, which is essential for maintaining a sterile environment. Having a septum within this specified range enhances the effectiveness of the dam during procedures such as restorative work, endodontics, and more.
